Five Star Epoxy Chock

Five Star Epoxy Chock is a precision-grade, 100% solids epoxy chocking system built for heavy-duty industrial installations that demand reliable equipment alignment and long-term performance. This two-component, pourable system is specifically designed for use under gas compressors, turbines, generators, pumps, and other critically aligned machinery. It delivers high compressive strength — even under elevated temperatures — and offers excellent flowability to ensure complete contact between the machinery base and foundation. Unlike traditional steel chocks, Five Star Epoxy Chock eliminates the need for machining, reduces installation time, and provides a chemically resistant, non-shrink solution that maintains its integrity under vibration, thermal cycling, and mechanical stress.

Key Features of Five Star Epoxy Chock

• High Compressive Strength
  Withstands up to 20,500 psi after post-cure, suitable for heavy-duty loads and dynamic machinery.
• Solvent-Free, 100% Solids
  Delivers consistent performance with no shrinkage or voids, even at elevated temperatures.
• Excellent Flowability
  Easy to pour and self-levels for tight-clearance placements and full surface contact.
• Thermal and Chemical Resistance
  Reliable up to 230°F (110°C) with resistance to oils, fuels, and industrial chemicals.
• Steel Chock Replacement
  Eliminates machining and ensures nearly 100% contact between baseplate and foundation.
• Fire-Resistant
  Self-extinguishing properties improve safety in high-risk environments.

Frequently Asked Questions

What makes Five Star Epoxy Chock different from traditional steel chocks?
It eliminates the need for machining and achieves near-total contact with the equipment base, saving time and improving alignment reliability.

Can it handle high temperatures?
Yes, it maintains structural integrity at service temperatures up to 230°F (110°C).

Is Five Star Epoxy Chock suitable for outdoor or marine applications?
While not specifically formulated for marine environments, it performs well in outdoor settings with proper surface preparation and sealing.

How thick can Five Star Epoxy Chock be poured?
Recommended pour depths range from ½ inch to 2½ inches. For other depths, contact a sales representative.

What is the typical cure time for Five Star Epoxy Chock?
At 70°F, cure time is 24 hours. Cure time shortens with higher temperatures and extends in cooler conditions.

How should I clean tools after use?
Tools should be cleaned immediately with MEK or similar solvent before the material hardens.
